3 TOGETHER, WE GET THE JOB DONE. UNIVIB 2 The newest small-scale vibrator from INOVA, the UNIVIB 2, delivers up to 34,000 lbs of peak force and is still agile enough to maneuver through dense terrains or sensitive environments with minimal impact. The newly engineered PLS-334 actuator allows operators to perform sweeps more consistently across a frequency bandwidth from 1 Hz to 400 Hz. Whether you are imaging deep reservoirs or shallow subsurface areas, the UNIVIB 2 offers the highest force-energy penetration in the industry for a vehicle of its class. The UNIVIB 2 is built with a high performance, 173 HP John Deere diesel engine that is available in Tier 3, Tier 4i, and Tier 4 Final options. This rugged engine provides enough power for the vehicle to effortlessly navigate through challenging terrains utilizing tires or tracks. When the engine is combined with an emission reducing after-treatment technology, the vibrator becomes certified to meet EPA Tier 4 Final and EU Stage 4 emissions regulations. With the operator in mind, INOVA designed the new cab to be more ergonomically comfortable while adding improved safety features and on-board diagnostics. The spacious cab is integrated with an operator escape hatch and a rollover protection structure (ROPS) that minimizes safety risks when operating the vehicle in hazardous environments. The cab also features a new CAN Bus based diagnostics tool that will provide real-time monitoring of the vehicle s health during source operations. With this tool, operators can feel more confident knowing their vehicle is performing within specifications. If potential issues should arise, they have the ability to quickly diagnose problems on-site or remotely to prevent downtime. The small-scale UNIVIB 2 vibrator shown with the new PLS-334 actuator can deliver up to 34,000 lbs peak force and can navigate easily through challenging terrains. UNIVIB The UNIVIB was specifically designed for source operations in environmentally restricted or heavily urbanized areas generating lower ground pressure while still outputting frequencies down to 1 Hz. This lighter, smaller, and mobile vibrator is built with the same quality and reliability of our traditional, fullsize AHV-IV vehicles. The rugged engine, durable framework, and serviceable design enable operators to increase operational efficiency and lower the cost of ownership. With a smaller vehicle footprint, the UNIVIB can navigate more freely through natural and man-made surroundings than larger vibrators. Furthermore, obtaining permitting access becomes less difficult for contractors since the environmental impact is reduced.
